Magnetic component and power conversion module

Abstract

Disclosed are a magnetic component and a power conversion module. The magnetic component includes a substrate and a coil winding. The substrate includes a winding portion, and a magnetic body is buried in the winding portion. A surface of the substrate is provided with a plurality of welding pads. The coil winding surrounds the winding portion and is arranged corresponding to the magnetic body. Two ends of the coil winding are respectively connected to two of the plurality of welding pads. Compared to existing magnetic component using a multilayer circuit board with planar windings on different layers of the multilayer circuit board, the above-mentioned magnetic component is formed by the coil winding surrounding the winding portion in which the magnetic body is buried, so that the DC resistance of the coil winding of the above-mentioned magnetic component is not increased due to the limitation of the number of layers of the substrate, and the dimension in a horizontal direction (i.e., the direction parallel to the surface of the substrate) can be reduced.
